This is a design obviously inspired by the Super Lion concept

I have a pencil drawing, with minimum specifications for a battlecruiser obviously inspired by the Super Lion. The maximum speed specified was 32 knots and the armament was 10-15in and 16-5in guns. I assumed that the armour basis was 9in. To be viable, this had to have lighter weight machinery. This is the Springsharp report:

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   57,533 lbs / 26,096 Kg = 34.1 x 15.0 " / 381 mm shells or 6.6 torpedoes
 Stability (Unstable if below 1.00): 1.13
 Metacentric height 6.7 ft / 2.0 m
 Roll period: 16.9 seconds

   - Recoil effect (Restricted arc if above 1.00): 0.92
 Seaboat quality  (Average = 1.00): 1.06

Hull form characteristics:
 Hull has rise forward of midbreak
 Block coefficient: 0.647
 Length to Beam Ratio: 7.69 : 1
 'Natural speed' for length: 28.28 kts
 Power going to wave formation at top speed: 56 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): 0.00 degrees

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 113.5 %
  - Above water (accommodation/working, high = better): 224.8 %
 Waterplane Area: 63,569 Square feet or 5,906 Square metres
 Displacement factor (Displacement / loading): 101 %
 Structure weight / hull surface area: 207 lbs/sq ft or 1,008 Kg/sq metre
